TECHNICAL FIELD

The present invention relates to a putter head of a golf club, and more particularly, to a putter head of a golf club capable of providing a more effective result in golfing by improving a top spin of golf ball rolling into a hole cup by a putting on a putting green and thus increasing a straightness that a progress direction of golf ball and a distance do not change even in a mistaken putting.

BACKGROUND

Recently, domestic men and ladies professional golfers have won with a very dominant level in international golf games of worldwide highest level such as PGA (Professional Golfers' Association) and LPGA (Ladies Professional Golf Association) etc., and it results in the rise of golf as popular sports and people enjoying golfing also increase in the nation.

Golf is played under the responsibility of an athlete alone unlike other sports without a comparatively great limit for a physical condition and so may be more interested by people, and men and women of all ages can enjoy the sports because golf is not strenuous exercise and thus there is no anxiety about injury.

On the other hand, not only a cause of influencing golf most greatly depends on a precise and flexible swing pose and a swing force, but also a golf club supporting that is a very important cause.

All golf clubs are classified as a head to strike a golf ball, and a shaft provided with a grip adapted at an uppermost part thereof, and according to shape and material of the head, the golf club is classified as three kinds of a wood for the purpose of fairway improvement, an iron to precisely drop a golf ball to a target point, and a putter to softly putt the golf ball on a putting green and push it into a hole cub.

In such putter, the length of shaft is relatively shortest among three kinds of golf clubs and thus it is easy to softly roll a golf ball, meanwhile, it is very sensitive to the putting and the sensitivity may be more important than a technological aspect. That is, it may be important to select a putter of a kind capable of providing a putting sense considering a technical aspect even in any shape.

On the other hand, a putting green is formed of a fine lawn having a relatively high even level, and to smooth it, a lawn mower to mow the lawn is used. At this time, the lawn may have an effect of leaning and biased toward one direction according to a mowing progress direction of the lawn mower, and when the golf ball rolls toward the hole cup on such uneven green, a forward progress of golf ball having a relatively weak top spin is impossible to go to an intended direction because of an effect curved in a lawn leaning direction.

In a head for a golf putter disclosed in Domestic Registration Utility Model No. 20-165375 provided by considering such use characteristic of putter, a sweet spot, that is a portion of golf ball hung down most effectively, is large and thus there is little a probability to be deviated into the right or left side in a putting and further a deviation of distance and direction is substantially reduced even in a mistaken putting.

FIG. 1 is a perspective view illustrating the configuration of a head for a golf putter according to a conventional art. As shown in FIG. 1, for a general golf putter head provided with a front striking part 901 and a rear weight reduction concave groove 903, a head 900 for a golf putter has the configuration that a striking part 901 is formed of a round unevenness head face 902 that is comprised of a plurality of round unevenness 905 formed in a transverse direction on a portion of front and lower faces of the head 900, and that a contact face 906 of lower face and front face in the striking part 901 is formed round downward in a rear face direction, and that an upper part of the weight reduction concave groove 903 has an opened shape.

According to the conventional art, the striking part 901 is formed of round unevenness 905 formed in the transverse direction, and thus a sweet spot portion of a golf club adequate to putt a golf ball is relatively large, and a top spin can be applied in a putting. Accordingly, distance and direction deviation of the golf ball is small even in a mistaken putting.

However, because only a plurality of unevenness 905 is formed in a simple array structure on a putter face of the head 900 and thus a putting range applied onto the golf ball is extremely minute as a contact-point type and further an effect to improve a top spin described above and substantially reduce a deviation of distance and direction of a golf ball falls considerably. Furthermore, respectively different golfing tendency every user and its deviation in a swing force cannot be solved, thus still causing an initial problem it is impossible to apply a top spin at user's desired level.

SUMMARY OF THE INVENTION

Accordingly, some embodiments of the invention provide a head for a golf putter capable of substantially reducing a deviation in a forward progress direction of golf ball through a spread of putting point momentarily changed to surround a portion of the golf ball by a putting collision when striking the golf ball and substantially increasing a straightness of the golf ball through an increase of top spin, by adapting a putting wire with tension.

According to an embodiment of the invention, a head for a golf putter comprises a head body united with a shaft endmost part of putter as a kind of golf club and used for putting a golf ball; a putting wire assembled in zigzags with a club face as a putter face of the head body, to extendedly strike the golf ball in a way of surrounding a portion of the golf ball in a putting using the putter; and a tension control member to change a striking sensitivity transferred to the golf ball in the putting through a tension control of the putting wire.

As described above, a head for a golf putter according to an embodiment of the invention employs a putting wire in zigzags on the front of club face, such that a striking force based on a spread of putting point provided in a type of surrounding a golf ball in a putting is directed toward a center of the golf ball, thereby obtaining a precise putting effect a progress direction of golf ball and a distance deviation do not become different even in a mistaken putting.

In addition, a relatively optimized condition such as a change determination of resilient force based on respective styles and swing force every user through a tension sensitivity control of the putting wire can be provided in a putting.

That is, a top spin of golf ball can be substantially increased with only a small swing track through a tension action surrounding a portion of the golf ball in a putting using the putting wire, thereby realizing a dominant straightness like a golf ball precisely sucked into a hole cup without being so greatly influenced from a leaning direction of lawn or a tilt of putting green.

On the other hand, FIGS. 6A and 6B are perspective view and disassembly perspective view of a head for a golf putter according to another embodiment of the invention. As shown in the drawings, to restrain a strong shaking of the putting wire 2 caused by a collision of putting and simultaneously substantially increase a resilient force, there may be further combined and adapted a pad support member 4 loaded into and combined with the inside of the concave block 1 a of the head body 1, and a cushion pad 5 supporting an inner side of the putting wire 2 in a state of being stuck to a front center part of the pad support member 4.

Further, the pad support member 4 is assembled with the concave block la through use of a combination bolt 41, and the cushion pad 5 is stuck to the pad support member 4 by using adhesive applied on the rear thereof.

In addition, an adhesion block 4 a to receive the cushion pad 5 is formed on the front of the pad support member 4, and a third gap keeping groove 5-1 connecting between the first and second gap keeping grooves 1-3 and 1-4 is formed on the front of the cushion pad 5, thereby realizing the acceptance and fixation for a gap keeping of the putting wire 2.

A non-described reference number p-11 is a grip combined and adapted on an uppermost part of the shaft so that a user grasps a putter by both hands.

Operation of the head A for a golf putter according to an embodiment is described in details as follows, with the configuration described above.

First, in the combination relation of the head A for a putter according to an embodiment of the invention, as shown in FIG. 3, one end of the putting wire 2 is inserted into insertion hole 1-1 formed on an upper side of the assembly block 1 b of the head body 1, and then the wrench bolt 11 is assembled in screw with the first bolt fastening hole 1-2, and pressurized and fixed thereto.

Then, the putting wire 2 is successively accepted into and fixed to the first, second gap keeping groove 1-3 and 1-4, and after that, the putting wire 2 is further wound onto the holding pin 12 of an uppermost side, and then its progress direction is returned and the putting wire 2 is applied and fixed to the first, second gap keeping groove 1-3, 1-4 of a lowermost side in its reverse order.

Through such repeated operations, the putting wire 2 covers the entire front of the concave block 1 a in zigzags, and another end part of the putting wire 2 is inserted into first bolt fastening hole 1-2′ formed on a lower side of the assembly block 1 b and simultaneously is pressurized and fixed by the wrench bolt 11′, and then a final assembly is executed.

Continuously, returned-side end parts of the putting wire 2 positioned at the side of first gap keeping groove 1-3 are individually hooked onto each of the holding hooks 32 of the tension control member 3, and then, the hinge parts 31 of the tension control member 3 are joined in a space between the support plates 13 of the assembly block 1 b and the protrusion block 14, and further the hinge pin 15 is successively inserted/assembled with the first, second and third hinge holes 13-1, 14-1 and 31-1, and thus the holding hook 32 of the tension control member 3 is movable pivotally.

Subsequently, the plurality of control bolts 33 pass through the bolt assembly holes 3-1 and simultaneously are assembled in screw with the third bolt fastening hole 1-5 and thus fixed to generate a tension of the putting wire 2 through the holding hook 32.

At this time, a tension sensitivity of the putting wire 2 is controlled with a consideration of swing tendency every user. That is, as shown in FIG. 4A, the tension sensitivity of the putting wire 2 can increase through the holding hook 32 to which the assembly block 1 b is closely stuck by tightening the control bolt 33 clockwise, or as shown in FIG. 4B, the holding hook 32 is distanced from the assembly block 1 b by loosening the control bolt 33 counterclockwise, thereby preventing a drop of tension sensitivity of the putting wire 2.

After completing the assembly of the putting wire 2 as described above, an endmost part of the shaft p-1 is inserted into and combined with the shaft insertion hole 1-10 formed in one side of upper part thereof as shown in FIG. 2, thereby producing one putter (p).

In putting a golf ball toward a hole cup by using the putter with the configuration described above on a putting green, a user carefully observes a tilt of green or tilt direction of lawn by lowering the waist before address and imagines how a golf ball rolls drawing a line and then addresses the ball toward its decided putting position and direction and then putts a central lower side of the golf ball.

When putting a golf ball as described above, the golf ball rolls toward a hole cup by a collision force and resilient force at a striking moment of the putting wire 2 provided along a swing track, and the putting wire 2 has a momentary transformation through the striking collision and a putting point is extended in a type of surrounding a portion of the golf ball as shown in FIG. 5. Such extended putting area prevents a great deviation change in forward progress distance and direction of golf ball even in a mistaken putting.
